I'm a noobie at learning java, and I don't know how to exactly 'compile'

http://java.sun.com/developer/onlineTraining/awt/contents.html#AWTIntroduction

I'm doing the first tutorial on that, and I'm wondering how to create a class file, to work this the AButton

I have the Applet webpage set up and my AButton.java file set up as:

import java.awt.Button; 
import java.applet.Applet; 
 
public class AButton extends Applet { 
  public void init() { 
    // STEP 1: Compose the GUI 
    Button beepButton = new Button("Beep");  
    add(beepButton); 
 
    // STEP 2: Setup Event handlers 
    beepButton.addActionListener(new Beeper()); 
 
    // STEP 3: Display the GUI (automatic -- this is an applet) 
  } 
}

When I open the page, I get:

load: class AButton.class not found.

How do I create a class file?

 

[Fate1]

You have to compile it.

In notepad type this

javac *.java
pause

Save it as compile.cmd Than put the java file in the same directory the compile.cmd is and run compile.cmd and it will create a class file.

 

[Iko]

Or you can do this:

Start>Run> "cmd"

Type "cd:\\ xxx \ xxx (directoanary where your file is ex: c:\\progam files\java)

and the write "javac xx (the file you want to compile)

you got it in the wrong place man...pm me
